22, 2 Muir: Fulgoroidea from Sumatra 175 



large process longer than broad, gradually widening from base 

 to middle, then gradually narrowing to the rounded apex. Anal 

 segment slightly longer than wide, apex broadly rounded. Gen- 

 ital styles fairly large, projecting beyond apex of pregenital 

 plate.

The specimens are much damaged, but the genitalia enable 

 me to identify this widely distributed species. 

 Zeugma corporaali sp. nov. Plate 1, fig. 5. 



In size, general build, and color this species is similar to Z. 

 monticola Kirkaldy (=Z. vittata Westwood?), but the genitalia 

 are quite distinct. In Z. corporaali sp. nov. the sedeagus is 

 longer and the apical, bifurcate portion has one large spine in 

 the middle on the side and a broad, bifurcate or subcrescent- 

 shaped process at apex ; it also has a series of trif urcate spines. 

 In Z. monticola Kirkaldy (Plate 1, fig. 6) the sedeagus is 

 shorter and the apical portion has two small spines in the middle 

 and a bidentate process at apex, and it has no trifurcate spines. 

 The lateral margins of the pygofer are also distinct. The female 

 of Z. corporaali differs from Z. monticola in having the basal 

 margin of the pregenital plate raised into a rim instead of a 

 small, raised rim forming a small arc slightly posterior to basal 

 margin. 



Sumatra, Medan, December 5, 1918 (Corporaal), 1 male, and 

 October 9, 1918 (Corporaal), 1 female. Type No. 1063. 



This genus is now known from Formosa, the Philippines, 

 Borneo, Java, Sumatra, Malay Peninsula, and India.
